The wedging key is of considerable length and projects inwardly to someextent beyond the collar 13 and the adjacent washer l6 and also extendsoutwardly to a considerable distance therefrom so that it can beconveniently driveiito position. In order that they may be of sufficientstrength, the wires, collars and wedges of the tie are 'preferablyformed of hard steel. The wedges may-be in theform of ordinary cut nailshaving parallelsides and tapered edges. However, as mostclearly shown inFig. 5, the width of the'wedge is slightly less than the widthbfthe slot12 in the collar, s0 that itwill be heldby the tie wires 10 out offrictional contact withthe col-' lar and rapable of exerting its maximumclampingaction upon the wires In the ,preferred form shown, the key 15,instead. of tagrooves or seats 19 which'fitthe wires and in crease thesurface, contact :andthe: grip of the wedgeuponthe wires.- Also, thewedge is provided with shOuldersQO having inclined grooves or seats for.the wiresand which are arrangedto spread the ends of the wires and bentor ofisetthem over the outer edgeof the I wardly through the opening andbetween the collar opening. In thisway, the ends of the -,wi1'esarecrimpedior interlocked with the collar tohold thelatter more firmlyin posi ,tion andprevent the spreading of the mold mus Preferably, also,the edges of the wedging key are provided with. recesses 21 between theshoulders 20 and the Wedge portion 18 which receivethe rounded bends ofthe wires and into which portions of the wires are slightly offset asthewedgeis driven to positionrto firmly interlock the latter with the,wedge. Obviously, with the arrangement shown, strain upon the tiedue tothe pouring of theconcrete will tighten the grip between the wires,collar and wedge.

A modifiedform of wedging key 15 is shown inQFigsUGjandi'Z; This form isprovided witha wedge portion 18 and inclined shoulders 20, but therecesses ,betweenthe wedge portion and shoulders are omitted.Preferably, as shown, the edges ofthe wiring seats "19'. in this form,are provided with nicks or notches 22 to form teeth for gripping thewires. g V I Asshownin Figs.3 and- 4, the washer 16 is provided with acircular opening 23 which is slightly less in diameter than the lengthties and the ties will stoutly resist pressure on the mold-walls so thatthe concrete can be rapidly poured. When the concrete has set, thetiewires can be readily cut to permit removal of the form and the wires canbe cut ofi flush with the face of the concrete or withdrawn.. therefrom,as. desired. .Also, if the wires are left in the concrete,theirlpro- 'jectingends can be readily twisted off by applyingza. wrenchto thetie collars which are preferablyv square. v
